Answer:

No, the rate is not proportional.

Step-by-step explanation:

If there are 45 marbles in 9 bags, we can assume that there are 5 marbles in each bag.

Going by that rate, we can do 5 * 36 = 180, NOT 150.

Thus, the rate is not proportional.

Another way to solve would be to do 45/9 and 150/36. If the rate is proportional, the answer for both should be the same.

However, 45/9=5 and 150/36=4.16666666667.

Those two answers are NOT equal.

Thus, the rate is not proportional.

Answer:

This code or is program to find a given value of derivative of a polynomial.

Step-by-step explanation:

We know already how to apply or make the procedures mathematically talking so this short program will eventually help you how to find logic.

// libraries

#include <stdio.h>

#include <conio.h>

//use to control floating elements

float poly(float a[], int, float);

//main

int main()

{

// Enter the degree of polynomial equation

float x, a[10], y1;

int deg, i;

printf("Enter the degree of polynomial equation: ");

scanf("%d", &deg);

printf("Ehter the value of x for which the equation is to be evaluated: ");

// Enter the coefficient of x to the power

scanf("%f", &x);

for(i=0; i<=deg; i++)

{

printf("Enter the coefficient of x to the power %d: ",i);

scanf("%f",&a[i]);

}

// The value of polynomial equation for the value of x

y1 = poly(a, deg, x);

printf("The value of polynomial equation for the value of x = %.2f is: %.2f",x,y1);

return 0;

}

/* function for finding the value of polynomial at some value of x */

float poly(float a[], int deg, float x)

{

float p;

int i;

p = a[deg];

for(i=deg;i>=1;i--)

{

p = (a[i-1] + x*p);

}

return p;

}

Answer:

$32.00

Step-by-step explanation:

$70 X .35 = $24.50 sneaker discount

$30 X .25 = $7.50 shirt discount

$24.50 + $7.50 = $32.00

In the game of Pick-A-Ball, there are 10 colored balls: 2 red, 4 white, and 4 blue. The balls have been placed into a small buck

MaRussiya [10]

Answer:

The probability of selecting the color of ball that you just selected(a red ball) is $P(r) = \frac{2}{10}$

Step-by-step explanation:

From the question we are told that

The total number of colored balls is n = 10

The number of red balls is r = 2 red

The number of white ball is w = 4

The number of blue balls is b = 4

The number of balls to be selected is N = 2 balls

The cost of playing picking a ball is c = $10

The winnings is $k = \$ P(A)$

Here P(A) is the probability of obtaining the exact sequence of result and from the question it is P(A) = 0.10

Generally my price according to the question is

$k = \frac{0.10 }{10}$

=> $k = 0.01$

Let assume we selected a red ball

Generally the probability of selecting a red ball is mathematically represented as

$P(r) = \frac{2}{10}$
